I employ a double decomposition and recomposition of Steam and said liquid hydrocarbon in the vaporization and combustion, so that the steam parts with a portion of oxygen that combines with the carbon, and the liberated hydrogen combines with the carbon in the process of combustion, thereby producing an intense heat, and preventing the escape of 1111- combined carbon in the form of smoke.

In the drawing, I have illustrated my invention by a vertical section. The portion a illustrates part of a steamboiler. It may, however, be any inclosure in which the heat is to act. Steam is admitted by the pipe I) from the boiler or other supply, and it is preferable to superheat the Same in the coil 0,' and convey the Same to the standpipe (I, tontiguous to the petroleum supply pipe 0, so that the said liquid hydrocarbon shall rise in the pipe f around the steam-pipe d, and be partially or entirely vaporized as the steam and vapors pass out into the chamber g, that is formed within the perforated cone or burner h. *The steam and petroleum vapors issuing from the burner-holes are ignited, and

burn with a rapidity, intensity, and length of flame proportioned to the condition of the'ap- Specification formingpart of Letters Patent -No. 149,931, dated April 21, 1874; application filed H No vember 25, 1873.

' paratus and the amount of liquid hydrocarbon Supplied. The combustion will be most perfect when the steam is of a sufficient temperature to vaporize the liquid hydrocarbon and promote the decomposition of the vapor in the flame, so that the oxygen of the water will combine with the carbon, and the hydrogen will also burn with the carbon in the presence of the atmospheric air. The proper amount of air is to be admitted into the furnace in any convenient manner, and atmospheric air may be forced into the burner with the steam.

The coil of wire within the chamber g promotes the proper admixture of the gases, and aids in heating them.

By filling the lower part of the apparatus with plaster-o'f-paris or non-conducting mate rial, as at k, the heat radiated downward is f and d, and non-conductin g material 70 below the vaponchamber g, as set forth.

2. The chamber 1 and burner h, combined with the coil of wire, introduced within the chamber g, and the steam and hydrocarbon supply-pipes, substantially as set forth.
